 Purpose and area of application
There are offered new structures of composite powders for gas-thermal hardening and recovery of details, which are used at the extreme conditions. Production of powders is executed by plasma-chemical synthesis of composite particles on the basis of refractory substances.

Advantages
|
| Increase of resistance of hot stamps details (t>10000C, strength of pressure is 250 t, abrasive) in 3-5 times in comparison with melting from powder wire of PP25H5FMS |
Increase of wear resistance in 2,5-4 times in comparison with coatings, which include WC-Co |
Increase of corrosion resistance in 3 times in comparison with TiO2 |
Technical characteristics
